DIRECTIONS
Make a yeast starter with the Wyeast American Ale strain at least 1 day prior to pitching.
Do a single infusion mash for 60 minutes at 155°F (68°C). Boil for 60 minutes following the schedule for hops and additions.
Pitch the yeast, lambic blend, and dregs at 65°F (18°C) and ramp up to 68°F (20°C) over 2 to 3 days. Bring the temperature up to the low 70s Fahrenheit (low 20s Celsius) to complete primary fermentation.
After 4 to 6 weeks in primary, rack to secondary, adding more bottle dregs, and age for 12 months.
After 12 months, rack onto the fruit puree and let age for another 4 months or to taste.
Bottle with rehydrated Champagne yeast or another dry yeast.
BREWER’S NOTES
Leave head space or use blow off tube for additional fermentation from the fruit.
